ing purposes. n,

-One of .the tobjyectsoi the invention is to i provide a housing whichcan be placed at any desired point within-a room or other en.

closure, said housing holding a grate in such. ainanner that practicallyall dangers result-v ing from thepuse of fuel inan vopen grate areeliminated, means being employed for controlling the flames sothat theywill Vnot which the housing is connected.

, A further Objectis yto utilize baftles'which," by deflecting theflames, also conserve heat and render the grate more eflicient as aheati ing medium. Y

A further ob'iect is to lprovide a structure vof this character whichcan be cleaned readily. l y ,A

With the foregoing `and lother objectsin view which will appear astherdescripti'on Vproceeds,'the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, itV being understood that changes intheprecise'einbodiment of the A yinvention herein disclosed may be madewithin the scope of what is claimed, withoutA 'departing from the spiritof the invention.

In the `accompanying drawings the preferred form of the invention hasbeenshown.

VIn said drawings7 Figurel 1 is a front elevation of a housing ilconstructed in .accordance with the present invention. l

, Referring to' the figures by characters of reference 1 designatesahousing preferably formed of sheet metal. This housing is open at thebottom where itis provided withair inlet apertures 2 in the front wall.The space` within the lower portion of the housing is sufficientlyVlarge` to lreceive a basket grate Gr, andirons, a gas burner, or thelike. The rear portion of the top of the housing is profl vided with anoutlet 3 from which products of combustion will escape through asuitable pipe into a chimney. Extending transversely within the'housingis a series of superposed baffle plates 47 these plates havingdownturned flanges 5 which are riveted orotherwise secured to the sidesand back of the housing. The baffles arepreferably inclined n linclosedpositions.

.downwardly 'j fo-rwardlyf their forward Clgs are spaced from-'-tlieYfront Wall of tlieghoi'ising ',:Secgured to tliejfront wall-of saidhousing.y and'tothe sidewalls j i are downturned vflanges 6 of anotherseries ing extended betweenfjbut spaced fromthe baflies 4.Afconcavereflector in the form of a plate 8 issecured tothe lower baflie4 and".Y

of superposed baffles-7'theserbaflesibeing inf i i clined downwardlyandrearwardly and be-A to the back wall of the housing so that prod-'u'cts of combustion coming thereagainstrwill y i be ldeflected into.the Vlower endV of ythe :tor-

tuous passage formed by the baffles 4 and?v i while the liglit rays.will be wardly and forwardly.l

reflectedl down- Foi-med Within the from of the -housingi close to thetop of each of the baffle plates -7 is a cleanout opening 9 and leachcleanout opening is normally closed by. mea-ns 0f a damper 10pivotallyconnected to the front of the housing-as shown at 11.` u

j The front of the housing 3 -isprovided.l

below'the lower baffle plate 7 with an'openfv f y are preferably@removably` mounted, therebeing a` longitudinal groove ing 12 adapted tobei' closed by doors13. These doors 14 in the lower edge portion of eachdoordesigned to receive the bottom wall of thedoor opening asrshown inFigure2 while latches indicated generally at 15 can be employed i forfastening` he upperportions ofthe doors By iiaingaie Corsis fromuiefopening 12 fuel can be placed in the grate Gr and. by

`leaving the door opening'uncovered, the heat Y from the burning fuelwill -radiate directly I through the opening 12. The'products ofcombustion will pass upwardly between the'` bafHes, .being compelled'tofollow atortuous i path. These baffles willprevent theflame fromentering the outlet 3 and will absorb i' much of the'hea't escapingupwardly. This" heat will be conducted through Vthe baffles to thevwalls of the structure and radiate'therefrom, thus increasing theeiliciency.l of the heater. By leaving the doors13 closed there 7 is nodanger of sparks iying` forwardly through the opening and ignitingarticles in close proximity to thevhousing.

It is to be understood of course that this structure can. be suitablyornamented and in The baiies can be fcleanedreadily lby shifthousing.
